People often say that the mineral is gold, silver, copper, iron, tin and other solid mineral. The oil and natural gas is a liquid, can be used as the fuel of combustible organic mineral, often buried deep in the ground.
The characteristics of oil and gas flow have determined that the distribution of oil and gas in underground space is more complicated than that of solid mineral. These complex dynamic processes occur in the long geological history period, it is difficult to directly observe the oil and gas exploration and development, and even difficult to obtain oil and gas flow traces. For a long time, the petroleum geologists have been working on the research, the search for the evidence and theory of oil and gas flow, to find more and better oil and gas.
